Advocates of Mars colonies commonly assert a supposed obligation to act so as to maximize the longevity of the human species. When this principle is defended, it is often by appeal to the alleged costs—of incoherence or misanthropy—of denying it. Against this supposed obligation, I argue for two theses. The modest thesis: it is not incoherent and need not be misanthropic to prefer human extinction sooner rather than later. The ambitious thesis: we should prefer human extinction sooner rather than later. (...) The supposed obligation to prolong our species is no justification of human activities in space. (shrink)

This theoretical study focuses on terraforming in the context of the industrially created image of the world by the mainstream media and on philosophical objections to the terraforming activities of humanity. The first part discusses the specific nature of the spectacularism of media images, while the second part explains the paradigmatic change in media images. The third part then turns to the ethically grounded binarism of current philosophical reflections on human expansion into space. The purpose of this study is to (...) consider objections to the mainstream media focus from the viewpoint of contemporary philosophy. The theoretical reflection is based on induction and deduction in order to point out the ambivalence of what humanity can do in the framework of progress in the sense of what it is capable of and in the sense of what is right.

The possibility of seeding other planets with life poses a tricky dilemma. On the one hand, directed panspermia might be extremely good, while, on the other, it might be extremely bad depending on what factors are taken into consideration. Therefore, we need to understand better what is ethically at stake with planetary seeding. I map out possible conditions under which humanity should spread life to other solar systems. I identify two key variables that affect the desirability of propagating life throughout (...) the galaxy. The first is axiological and depends on which value theory in environmental ethics is correct. The second is empirical and depends on whether life is common or not in our region of the universe. I also consider two ethical objections to an interplanetary life-seeding mission: the risk of interfering with indigenous life and the risk of increasing suffering in our galaxy. (shrink)

Según el largoplacismo, los efectos a largo plazo de nuestras acciones son un aspecto crucial de las mismas. Esto se debe a que el futuro, dada su extensión, presumiblemente contendrá a la mayor parte de los seres que alguna vez existan. Hay, sin embargo, distintas objeciones que cuestionan la viabilidad de la propuesta largoplacista, señalando que tendríamos razones para priorizar el corto plazo. Estas objeciones apuntan a problemas relacionados con la representación de individuos que todavía no existen, la situación de (...) las generaciones futuras o la incertidumbre acerca de lo que ocurrirá en el largo plazo. Este artículo examina dichas objeciones y argumenta que ninguna de ellas supone una razón decisiva para rechazar el largoplacismo. (shrink)

With the end of the Cold War, political and ideological competition has decreased as a stated reason for space exploration. The possibility of establishing a settlement on Mars is being seriously evaluated by state and commercial space agencies, which includes objectives to expand human civilization and ensure the continuity of the human species. The technological challenges associated with space settlement continue to receive significant attention, but the success of space settlement will also depend on other human factors. This study presents (...) a high-level overview of some potential issues that could arise with the development of a permanent populationand a space economyon Mars. This study highlights some of the anticipated problems of overnance, trade, production, and proliferation that will need pragmatic solutions to ensure the sustainability of a martian settlement. This paper is intended to instigate further discussion and research regarding human and economic factors that could enable or constrain future settlements on Mars. (shrink)

Ian Stoner has recently argued that we ought not to colonize Mars because doing so would flout our pro tanto obligation not to violate the principle of scientific conservation, and there is no countervailing considerations that render our violation of the principle permissible. While I remain agnostic on, my primary goal in this article is to challenge : there are countervailing considerations that render our violation of the principle permissible. As such, Stoner has failed to establish that we ought not (...) to colonize Mars. I close with some thoughts on what it would take to show that we do have an obligation to colonize Mars and related issues concerning the relationship between the way we discount our preferences over time and projects with long time horizons, like space colonization.

If we had the ability to terraform Mars, would it be morally permissible to do it? This article surveys three preservationist arguments for the conclusion that we should not terraform Mars and three interventionist arguments that we should. The preservationist arguments appeal to a duty to conserve objects of special scientific value, a duty to preserve special wilderness areas, and a duty not to display vices characteristic of past colonial endeavors on Earth. The interventionist arguments appeal to a duty to (...) fulfill our pioneering nature, a duty to extend the lifespan of our species, and a duty to restore the ecosystems Mars may once have housed. The preservationist arguments are stronger than the interventionist arguments; terraforming Mars is probably morally wrong. (shrink)

Approaching the settlement of our Moon from a practical perspective, this book is well suited for space program planners. It addresses a variety of human factor topics involved in colonizing Earth's Moon, including: history, philosophy, science, engineering, agriculture, medicine, politics & policy, sociology, and anthropology. Each chapter identifies the complex, interdisciplinary issues of the human factor that arise in the early phases of settlement on the Moon. Besides practical issues, there is some emphasis placed on preserving, protecting, and experiencing the (...) lunar environment across a broad range of occupations, from scientists to soldiers and engineers to construction workers. The book identifies utilitarian and visionary factors that shape human lives on the Moon. It offers recommendations for program planners in the government and commercial sectors and serves as a helpful resource for academic researchers. Together, the coauthors ask and attempt to answer: “How will lunar society be different?”. (shrink)

In this article, the idea of space colonization is critically examined by drawing from Martin Heidegger’s topological philosophy of technology and dwelling. Heidegger’s ideas from his 1966 interview with German journal Der Spiegel are examined in light of his relevant philosophical texts to interpret his claims concerning The Blue Marble image. This article defends the view that Heidegger does not take a moral stance against space colonization as such; rather, he elucidates the existential grounds of our relation to modern technology, (...) and the sense of unsettledness that stems from the lack of an appropriate relation to place.
